Contour interpolator for polygonal data.
Contour interpolator for to place points on polygonal surfaces.
int InterpolateLine(vtkRenderer *ren, vtkContourRepresentation *rep, int idx1, int idx2) override
Subclasses that wish to interpolate a line segment must implement this.
void PrintSelf(ostream &os, vtkIndent indent) override
Standard methods for instances of this class.
double DistanceOffset
Draw the polyline at a certain height (in the direction of the vertex normal) above the polydata.
